[0014] The signal conditioning circuit is electrically connected to the antenna and is configured to convert the received digital signal into an analog signal to transmit the analog signal to the antenna, or to convert the received analog signal into a digital signal to transmit the digital signal to the sub-controller.

[0015] The antenna is configured to generate electromagnetic waves based on received analog signals, or to generate analog signals based on received electromagnetic waves.

[0016] In some embodiments, the system wireless control unit includes a local wireless controller;

[0017] The local wireless controller is wirelessly connected to the data acquisition transceiver to receive operating data sent by the wireless communication control unit, or to send control commands to the wireless communication control unit.

[0018] In some embodiments, the data acquisition transceiver has a first wired communication interface;

Detailed Implementation

[0037] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0038] In the description of this utility model, the term "exemplary" is used to mean "serving as an example, illustration, or description." Any embodiment described as "exemplary" in this application is not necessarily to be construed as being more preferred or advantageous than other embodiments. The following description is provided to enable any person skilled in the art to implement and use this utility model. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that this utility model can be implemented without using these specific details. In other instances, well-known structures and processes will not be described in detail to avoid obscuring the description of this utility model with unnecessary detail. Therefore, this utility model is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0039] This application provides a communication system and an energy storage power station, which will be described in detail below.

[0040] First, refer to Figure 1 , Figure 1A schematic diagram of a communication system in an embodiment of this application is shown. The communication system is applied to an energy storage power station, which includes multiple operating devices. The communication system includes multiple wireless communication control units 10, data acquisition transceivers 20, and system wireless control units 30.

[0041] Specifically, multiple wireless communication control units 10 correspond one-to-one with multiple operating devices. Each wireless communication control unit 10 can receive control commands from the corresponding operating device or send operating data from the corresponding operating device. For example, taking a battery module as an operating device, the wireless communication control unit 10 can send data such as the battery module's voltage, current, and temperature as operating data, so that the system wireless control unit 30 can receive the battery module's operating data through the data acquisition transceiver 20. As another example, taking a liquid cooling unit as an operating device, the wireless communication control unit 10 can receive cooling control commands sent by the system wireless control unit 30 through the data acquisition transceiver 20, so that the liquid cooling unit can cool the battery module according to the cooling control commands.

[0042] Understandably, the types of operating equipment are not limited to this. In some possible embodiments, multiple operating devices may also include a battery management system, an energy storage converter, a smart communication unit, a fire protection system, a combustible gas sensor, video surveillance, an air conditioner, operating indicator lights, etc.

[0043] For example, the wireless communication control unit 10 may include, but is not limited to, a LoRa (Long Range) communication module, a Bluetooth communication module, a Wi-Fi communication module, a 3G wireless communication module, a 4G wireless communication module, or a 5G wireless communication module.

[0044] The data acquisition transceiver 20 is wirelessly connected to each wireless communication control unit 10. The data acquisition transceiver 20 can receive operating data sent by each wireless communication control unit 10, such as voltage, current, power, remaining battery capacity, battery health status, temperature, and chargeable or dischargeable power. Simultaneously, the data acquisition transceiver 20 can forward control commands sent by the system wireless control unit 30 to each wireless communication control unit 10 to control the operation of various devices in the energy storage power station. For example, control commands sent to the wireless communication control unit 10 corresponding to the battery module can control the charging / discharging of the battery module; similarly, control commands sent to the wireless communication control unit 10 corresponding to the energy storage converter can control the energy storage converter to perform voltage conversion.

[0045] It should be noted that the data acquisition transceiver 20 can convert data or commands supporting the data sender's communication protocol into data or commands supporting the data receiver's communication protocol. For example, if a wireless communication control unit 10 supports Modbus TCP (Modbus Transmission Control Protocol) and the system wireless control unit 30 supports Modbus RTU (Modbus Remote Terminal Unit), when the wireless communication control unit 10 sends operational data as a data sender based on the Modbus TCP communication protocol, the data acquisition transceiver 20 can convert the data supporting the Modbus TCP communication protocol into data supporting the Modbus RTU communication protocol to meet the communication protocol requirements of the system wireless control unit 30. Conversely, when the system wireless control unit 30 sends control commands as a data sender based on the Modbus RTU communication protocol, the data acquisition transceiver 20 can convert the data supporting the Modbus RTU communication protocol into data supporting the Modbus TCP communication protocol to meet the communication protocol requirements of the wireless communication control unit 10.

[0046] It is understood that the communication protocols that the data acquisition transceiver 20 can switch to are not limited to this. For example, the communication protocols that the data acquisition transceiver 20 can switch to may include, but are not limited to, Modbus TCP, Modbus RTU, IEC103 (Telecontrol equipment and systems for electric power systems - Part 103), IEC104 (Telecontrol equipment and systems for electric power systems - Part 104), IEC61850 (Telecontrol equipment and systems for electric power systems - Part 61850), or CAN (Controller Area Network) and other communication protocols.

[0047] The system wireless control unit 30 is wirelessly connected to the data acquisition transceiver 20. The system wireless control unit 30 can receive operating data sent by the wireless communication control unit 10 through the data acquisition transceiver 20, or the system wireless control unit 30 can send control commands to the wireless communication control unit 10 through the data acquisition transceiver 20. For example, the wireless communication control unit 10 sends the chargeable power of the battery module as operating data. The system wireless control unit 30 receives the chargeable power sent by the wireless communication control unit 10 through the data acquisition transceiver 20. Then, the system wireless control unit 30 determines the charging power of the battery module based on the chargeable power and sends a charging power control command to the wireless communication control unit 10 through the data acquisition transceiver 20, thereby controlling the charging power of the battery module through the charging power control command.

[0048] Those skilled in the art will understand that the control commands sent by the system wireless control unit 30 can be set according to actual needs (such as the function of the energy storage power station and the type of operating equipment), and this application does not make any specific limitations.

[0049] In this embodiment, the data acquisition transceiver 20 is wirelessly connected to each wireless communication control unit 10, and the system wireless control unit 30 is wirelessly connected to the data acquisition transceiver 20. This allows the system wireless control unit 30 to receive operating data sent by the wireless communication control unit 10 or send control commands to the wireless communication control unit 10 through the data acquisition transceiver 20. Since the wireless communication control unit 10, the data acquisition transceiver 20, and the system wireless control unit 30 communicate wirelessly, when the communication system is applied to an energy storage power station, the energy storage power station does not need to connect each operating device through communication cables. This solves the problem of messy communication cables and inconvenient operation and maintenance caused by a large number of operating devices in the energy storage system.

[0050] Meanwhile, since the data acquisition transceiver 20 can convert data or instructions that support the data sender's communication protocol into data or instructions that support the data receiver's communication protocol, the data acquisition transceiver 20 can perform communication protocol conversion uniformly, thus eliminating the need to set up a communication protocol conversion circuit in each wireless communication control unit 10 and the system wireless control unit 30, which helps to reduce the cost of the communication system.

[0051] In some embodiments of this application, see Figure 2 , Figure 2 Another schematic diagram of the communication system in this application embodiment is shown, wherein the data acquisition transceiver 20 includes a plurality of communication protocol conversion units 21, each communication protocol conversion unit 21 is configured to convert received data or instructions into a target communication protocol, and at least two communication protocol conversion units 21 correspond to different target communication protocols.

[0052] For example, one communication protocol conversion unit 21 targets the IEC 103 communication protocol and can convert data or instructions of the Modbus TCP communication protocol into data or instructions of the IEC 103 communication protocol; another communication protocol conversion unit 21 targets the IEC 61850 communication protocol and can convert data or instructions of the Modbus TCP communication protocol into data or instructions of the IEC 61850 communication protocol. Therefore, it can be ensured that the data acquisition transceiver 20 outputs data or instructions of different target communication protocols through multiple communication protocol conversion units 21, which meets the multi-communication protocol communication requirements of the communication system of this application.

[0053] In some embodiments of this application, any two communication protocol conversion units 21 may correspond to different target communication protocols. For example, in embodiments where the communication system supports communication protocols including Modbus TCP, Modbus RTU, IEC103, IEC104, and IEC61850, the data acquisition transceiver 20 may be configured with five communication protocol conversion units 21. The target communication protocols of these five communication protocol conversion units 21 are Modbus TCP, Modbus RTU, IEC103, IEC104, and IEC61850, respectively, to convert the data or instructions received by the data acquisition transceiver 20 into data that supports the communication protocols Modbus TCP, Modbus RTU, IEC103, IEC104, and IEC61850.

[0054] In some embodiments of this application, see Figure 3 , Figure 3 Another schematic diagram of the communication system in this application embodiment is shown, wherein the data acquisition transceiver 20 has at least one wired communication interface 201; the wired communication interface 201 is wiredly connected to the system wireless control unit 30. Therefore, for the system wireless control unit 30, in addition to receiving data or sending commands wirelessly, it can also receive control commands or send operating data through the wired communication interface 201. When wireless communication (or wired communication) is lost due to a fault, it can automatically switch to wired communication (or wireless communication) mode, thereby improving the reliability of communication and preventing the risk of the energy storage power station becoming uncontrollable due to the collapse of a single communication method.

[0055] It should be noted that although the data acquisition transceiver 20 is wired to the system wireless control unit 30 via the wired communication interface 201 in the above embodiments, the number of system wireless control units 30 is relatively small compared to the multiple operating devices of the energy storage power station. Therefore, the above embodiments will not lead to the energy storage power station adding too many wired communication cables. That is, the above embodiments will not lead to the problem of messy communication cables and inconvenient operation and maintenance in the energy storage system.

[0056] For example, the wired communication interface 201 may include, but is not limited to, an Ethernet communication interface, an RS-232 communication interface, an RS-485 communication interface, or a DIDO communication interface.

[0057] In some embodiments of this application, see Figure 4 , Figure 4 A schematic diagram of a wireless communication control unit 10 in an embodiment of this application is shown, wherein each wireless communication control unit 10 includes a sub-controller 11, a signal conditioning circuit 12, and an antenna 13.

[0058] Specifically, the sub-controller 11 is electrically connected to the signal conditioning circuit 12 to send digital signals to or receive digital signals sent by the signal conditioning circuit 12; the signal conditioning circuit 12 is electrically connected to the antenna 13, and the signal conditioning circuit 12 can convert the received digital signals into analog signals to send analog signals to the antenna 13, or the signal conditioning circuit 12 can convert the received analog signals into digital signals to send digital signals to the sub-controller 11.

[0059] For example, when the sub-controller 11 sends a digital signal to the signal conditioning circuit 12, the signal conditioning circuit 12 can convert the received digital signal into an analog signal for output. After receiving the corresponding analog signal, the antenna 13 can generate electromagnetic waves with specific frequency, amplitude, and other characteristics based on the received analog signal, thereby realizing the operation data transmission function of the wireless communication control unit 10. Conversely, when the antenna 13 receives electromagnetic waves, the antenna 13 can generate an analog signal based on the received electromagnetic waves and output it to the signal conditioning circuit 12. The signal conditioning circuit 12 can convert the received analog signal into a digital signal for output. After the sub-controller 11 receives the digital signal, it realizes the control command reception function of the wireless communication control unit 10.

[0060] For example, the sub-controller 11 may include, but is not limited to, a general-purpose processor, a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc. The signal conditioning circuit 12 may include an analog-to-digital converter, a digital-to-analog converter, etc., to convert analog signals into digital signals via an analog-to-digital converter, or to convert digital signals into analog signals via a digital-to-analog converter.

[0061] It is understood that the data acquisition transceiver 20 and the system wireless control unit 30 may also include circuits / modules similar to the wireless communication control unit 10 to realize wireless communication functions, which will not be described in detail here.

[0062] In some embodiments of this application, see Figure 5 , Figure 5 Another schematic diagram of the communication system in this application embodiment is shown, wherein the system wireless control unit 30 includes a local wireless controller 31; the local wireless controller 31 is wirelessly connected to the data acquisition transceiver 20 to receive operating data sent by the wireless communication control unit 10 through the data acquisition transceiver 20, or to send control commands to the wireless communication control unit 10 through the data acquisition transceiver 20.

[0063] It should be noted that the local wireless controller 31 is the control unit of the energy storage battery cabinet in the energy storage power station. Generally, there are multiple energy storage battery cabinets in an energy storage power station. Therefore, the communication system of this application may include multiple local wireless controllers 31 to coordinately control the lower-level controlled operating equipment in each energy storage battery cabinet to execute control strategy commands, thereby realizing the system-level function of the energy storage battery cabinet unit. For example, taking an energy storage battery cabinet equipped with battery modules, a battery management system, an energy storage converter, an air conditioner, and operation indicator lights as an example, the local wireless controller 31 receives operating data or sends control commands through the data acquisition transceiver 20, thereby controlling the battery modules, battery management system, energy storage converter, air conditioner, and operation indicator lights to execute control strategy commands.

[0064] In some embodiments of this application, see further reference. Figure 5The data acquisition transceiver 20 has a first wired communication interface 202. The first wired communication interface 202 is wired to the local wireless controller 31. Therefore, in addition to receiving data or sending commands wirelessly, the local wireless controller 31 can also receive control commands or send operating data through the first wired communication interface 202. This can improve the reliability of communication of the local wireless controller 31 and prevent the risk of the energy storage battery cabinet becoming uncontrollable due to the failure of a single communication method.

[0065] In some embodiments of this application, see Figure 6 , Figure 6 Another schematic diagram of the communication system in this application embodiment is shown, wherein the system wireless control unit 30 further includes an energy management wireless controller 32; the energy management wireless controller 32 is wirelessly connected to the data acquisition transceiver 20 to receive operating data sent by the wireless communication control unit 10 or the local wireless controller 31 through the data acquisition transceiver 20, or to send control commands to the wireless communication control unit 10 or the local wireless controller 31 through the data acquisition transceiver 20.

[0066] It should be noted that the energy management wireless controller 32 is the energy control unit of the entire energy storage power station. The energy management wireless controller 32 is responsible for monitoring, controlling, and optimizing the energy flow and operating efficiency of the energy storage power station, thereby realizing energy monitoring and management. For example, the energy management wireless controller 32 receives operating data sent by the wireless communication control unit 10 or the local wireless controller 31 through the data acquisition transceiver 20, thereby monitoring the operating status of the energy storage power station in real time (e.g., battery status, charging and discharging status). Furthermore, the energy management wireless controller 32 can send control commands to the wireless communication control unit 10 or the local wireless controller 31 through the data acquisition transceiver 20 based on factors such as grid demand and electricity price fluctuations, causing the energy storage power station to store or release energy, thereby dynamically adjusting the operating mode of the energy storage power station.

[0067] In some embodiments of this application, see further reference. Figure 6 The data acquisition transceiver 20 has a second wired communication interface 203. The second wired communication interface 203 is wiredly connected to the energy management wireless controller 32. Therefore, in addition to receiving data or sending commands wirelessly, the energy management wireless controller 32 can also receive control commands or send operating data through the second wired communication interface 201. This can improve the reliability of the communication of the energy management wireless controller 32 and prevent the risk of energy management failure of the energy storage power station due to the failure of a single communication method.

[0068] Furthermore, to better implement the communication system in the embodiments of this application, this application also provides an energy storage power station based on the communication system. The energy storage power station includes the communication system as described in any of the above embodiments. Since the energy storage power station in the embodiments of this application has all the beneficial effects of the above-described communication system due to the inclusion of the communication system, it will not be described in detail here.

[0069] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the detailed descriptions of other embodiments above, which will not be repeated here.
